Apple stops signing iOS 9.3.3: Downgrade from iOS 9.3.4 to iOS 9.3.3 is not possible

Apple has
stopped signing iOS 9.3.3 firmware for
all the iOS devices like iPhone, iPad and iPod Touch which means that
users can no longer downgrade their iOS to that version using iTunes.

Now you
can’t downgrade to iOS 9.3.3 on iPhone, iPad and iPod touch, as Apple stops signing iOS 9.3.3 so if you
are on iOS 9.3.4 and
also cannot upgrade to iOS 9.3.3, if you are on lower versions. So
basically you are forced to upgrade to iOS 9.3.4 directly. If you
have accidently update your device via OTA, then there is not to downgrade back
to iOS 9.3.3 now as Apple stops signing iOS 9.3.3.

Apple always
gives two versions of iOS to restore whenever it releases a new version.
So that people have ability to downgrade their devices to the
previous version if they are not satisfied with the new one. But after some
time, it stops signing the previous version.

firmware.

Note: If
you are on lower iOS versions like 9.3.3, 9.3.2, 9.2 stay away from update
because jailbreak is only available on lower version of iOS. If you are a
jailbreakers, do not upgrade to iOS 9.3.4 as there is no jailbreak
for iOS 9.3.4. So it’s better to stay on older version of iOS for now.
